It was just called "Stanza Wagon" in the US. "Wagovan" was a name used by Honda on slightly decontended midyear versions of their Civic wagon they'd bring out every so often in the 80s to get around import quotas at the time. The Wagovans usually had a little metal bar across the inside of each rear quarter window to protect the glass from shifting cargo (as if anyone used them for that, but that was where the "Wagovan" name came from).
